# Colours The MiVoice Office 400 CCS Apps initially use a default colour scheme when displaying data graphically, but it's possible for Users to configure their own set of colours for use by the Apps whenever they log in. The Wallboard App will use the System User's colour scheme if there is one configured, otherwise it will use the default scheme.
## Colour Description This indicates when the colour will be used in the Apps. For example; when showing answered calls graphically all Apps will use a fill colour of '#afcc5e' and a text (font) colour of 'white'. ANy colour can be entered, for either fill or font, and a particular colour can be used more than once.
## Fill Colour This is the colour that any shaded area, chart bar, line, column or pie slice, etc, will be filled with when the Apps display the named statistic or state as a series on a chart or as an element in some dynamic graphics. Use the drop down arrow to open a colour selection window. Choose the colour you want and press the drop down arrow again to close the selection window. Any changes you make must be applied. Apps that are already running will automatically begin to use the new colours after then have been applied, but it takes several seconds for the changes to filter through.
## Font Colour When changing a Fill colour it's important to remember the Font colour. This is the colour of any text displayed over the fill colour, such as names, times and values. The text could be difficult to read unless an appropriate colour is selected. You are not limited to just black or white, any colour can be used. Again, any changes must be applied.
## Apply changes All changes must be applied before they will take effect. Press Cancel to return all colours to the last applied state.
## Restore Default Colours If you decide the scheme you have set up is no longer suitable, rather than change each colour individually, click Restore Defaults to instantly return your colour scheme back to the installatuion default configuration. CAUTION: You do not need to Apply this change, your colour scheme will immediately be returned to the default scheme when you click this button.
